Error while using ListFragement

Error while using ListFragement - java

I am developing an android app for online payment for which I want to display Lists of restaurants under the tab named Restaurants. Same as this some other tabs will have list below them and a few tabs will have form under them (if possible and not difficult otherwise I will stay with the lists only)
Here is the code I have written. It contains an error in the Adapter class and may be some logical errors which I am not sure about as this is my first ever android app.

Fragment holding a RecyclerView not showing in the MainActivity

I'm trying to show a RecyclerView, in a fragment, in my main activity.
I'm not getting any errors, but the fragment remains empty, and I can't find the solution for this problem.
I simply have a fragment that has a recyclerview in it, I configure the recyclerview in HomeFragment.java, then in the MainParkActivity, I have a FrameLayout, which is replaced with the HomeFragment.
MainParkActivity
package com.example.ipark;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;

public class MainParkActivity extends AppCompatActivity {
private static final String TAG = "MainParkActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d(TAG, "onCreate: started.");
Toolbar toolbar = findViewById(R.id.toolbar);
Fragment homeFragment = new HomeFragment();
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("iParc");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, homeFragment).commit();
}
}

In your fragment_home.xml, your Recyclerview has layout_height and layout_width 0dp. Change it to match_parent. Everything else in your code is correct. I'd have commented it, but I currently do not have commenting privileges! Accept it if you found it helpful!

In your activity_main layout, you have app:layout_constraintBottom_toTopOf="parent"
It should be app:layout_constraintBottom_toBottomOf="parent"
Your layout is currently displaying above the screen in your fragment.

use
adapter.notifyDataSetChanged();
after setting the adapter for RecycleView.

Recycler View not showing in fragment

I have three fragments: Fragment user, Fragment Home and Fragment Progress.
I'm trying to implement a recylcer view in the homefragment that can recycle images in the recycler view nothing is happening and no error is showing in logcat, i don't know what i'm doing wrong.
1.This is my Custom Adapter:
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.Collections;
import java.util.List;
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder>{
#NonNull
private LayoutInflater inflator;
List<Information> data= Collections.emptyList();
public CustomAdapter(Context context, List<Information> data){
inflator= LayoutInflater.from(context);
}
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view=inflator.inflate(R.layout.customlayout, parent,false);
MyViewHolder holder=new MyViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
Information current=data.get(position);
holder.icon.setImageResource(current.images);
holder.title.setText(current.title);
}
#Override
public int getItemCount() {
return 0;
}
class MyViewHolder extends RecyclerView.ViewHolder{
ImageView icon;
TextView title;
public MyViewHolder(View itemView) {
super(itemView);
icon = (ImageView) itemView.findViewById(R.id.listicon);
title = (TextView) itemView.findViewById(R.id.textView);
}
}
}
This is my Fragment

private CustomAdapter adapter;
int[] IMAGES = {R.drawable.abs,R.drawable.arms,R.drawable.back,R.drawable.chest,R.drawable.full,R.drawable.legs};
private RecyclerView recyclerView;

private String mParam1;
private String mParam2;
public HomeFragment() {
}
public static HomeFragment newInstance(String param1, String param2) {
HomeFragment fragment = new HomeFragment();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
}
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.fragment_home, container, false);
recyclerView =(RecyclerView) layout.findViewById(R.id.drawerList);
adapter = new CustomAdapter(getActivity(), getData());
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
return layout;
}
public static List<Information> getData(){
List<Information> data = new ArrayList<>();
int [] icons = {R.drawable.abs,R.drawable.arms,R.drawable.back,R.drawable.chest,R.drawable.full,R.drawable.legs};
String[] titles={"Abs","Arms","Back","Chest","full","legs"};
for (int i=0; i<icons.length && i<titles.length;i++){
Information current = new Information();
current.images=icons[i];
current.title=titles[i];
data.add(current);
}
return data;
}
}
I can't see to find what I'm doing wrong.

you didnt assign the data in your adapter's constructor
this.data = data;
then your item count should be
data.size();
should not be 0.

thanks for helpme.

There is a simple tutorial for your purpose. You can check this link.
But it replace fragments when normal button clicked. You can just simply move the codes into your tab's click event. Just like that : See the link
If you already added fragment1 and fragment2 into viewpager1 and fragment1A and fragment2A into viewpager2 and if you want to just simply switch the fragments programmatically when you clicked the tabs, then you can use viewpager1.setCurrentItem(1)
viewpager1.setCurrentItem(0) in tabs' click events.

How to display two fragments at the same time using TabLayout?

I use Android Tab Example with two tabs, view pager and fragments (structure on the image):
For get fragments i use the solution from this post.
When my device is rotation i want to display two fragments at the same time.

How to add dynamically several fragments

I create a little app with 3 static fragments and a view pager adapter. But what I want is to create Only one kind of fragment and with a button "add" , add other fragment which will be adapted by the view pager.. here is what i have done
FragmentTab1.java ; FragmentTab2 ; FragmentTab3 have the same code
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentTab2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Get the view from fragmenttab2.xml
View view = inflater.inflate(R.layout.fragmenttab2, container, false);
return view;
}
}
here is my MainActivity.java
import android.app.Fragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
//Button adfg = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
// Locate the viewpager in activity_main.xml
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
// Set the ViewPagerAdapter into ViewPager
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
}
}
ViewPagerAdapter.java
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class ViewPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 3;
// Tab Titles
private String tabtitles[] = new String[] { "Tab1", "Tab2", "Tab3" };
Context context;
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public Fragment getItem(int position) {
switch (position) {
// Open FragmentTab1.java
case 0:
FragmentTab1 fragmenttab1 = new FragmentTab1();
return fragmenttab1;
// Open FragmentTab2.java
case 1:
FragmentTab2 fragmenttab2 = new FragmentTab2();
return fragmenttab2;
// Open FragmentTab3.java
case 2:
FragmentTab3 fragmenttab3 = new FragmentTab3();
return fragmenttab3;
}
return null;
}
#Override
public CharSequence getPageTitle(int position) {
return tabtitles[position];
}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"

<android.support.v4.view.PagerTabStrip
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:textColor="#000000" />
</android.support.v4.view.ViewPager>
fragmenttab1.xml ; fragmenttab2.xml ; fragmenttab3.xml has the same code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"

<Button

</LinearLayout>

You need to create a method to add the fragment on the subclass of FragmentPagerAdapter, more or less like this :
//use those lists
private List<Fragment> listFragment = new ArrayList<Fragment>();
private List<String> listFragmentTitle = new ArrayList<String>();
private List<Integer> listFragmentIcon = new ArrayList<Integer>();
public void addTab(Fragment fragment,String title, int icon) {
listFragment.add(fragment);
listFragmentTitle.add(title);
listFragmentIcon.add(icon);
}
#Override
public Fragment getItem(int position) {
// TODO Auto-generated method stub
return listFragment.get(position);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return listFragment.size();
}
Then you just need to use it on the subclass of Activity, example :
//create a private method to set a new - dynamic fragment in the ACTIVITY
private Fragment setFragment(int pos)
{
MyFragment myFragment = new MyFragment();
Bundle data = new Bundle();
data.putString("test", "test");
myFragment.setArguments(data);
return myFragment;
}
Finally, add the fragment (for example, inside an onClickListener) :
//INSIDE an onClickListener
pagerAdapter.addTab(setFragment(position), getItem(position).getName(), R.drawable.ic_launcher);

this is my MainActivity.java class #BlazeTama
package com.light.frag;
import com.light.frag.R;
import com.light.frag.ViewPagerAdapter;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends FragmentActivity implements OnClickListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Locate the viewpager in activity_main.xml
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
// Set the ViewPagerAdapter into ViewPager
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
Button ajou = (Button) findViewById(R.id.bajou);
ajou.setOnClickListener(this);
}
private Fragment setFragment(int pos)
{
MyFragment myFragment = new MyFragment();
Bundle data = new Bundle();
data.putString("test", "test");
myFragment.setArguments(data);
return myFragment;
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bajou:
ViewPagerAdapter.addTab(setFragment(position), getItem(position).getName(), R.drawable.ic_launcher);
break;
}
}
}
